3. according to intelligent wireless tunnel fire hazard monitoring system described by claim 2, it is characterized in that using ZigBee pattern to communicate in system between all of monitoring unit, between system master controller and Fire Control Cabinet, data-interface is communicated by RS232/RS485.
4. a tunnel fire hazard intelligent wireless monitoring system and method, it is characterised in that comprise the steps:
A. fire protection control room side master controller, controller of fan, fire detector, fire warner, fire broadcast controller, data force transfer controller (router) opening initialization, sets up wireless monitor network based on ZigBee automatically；
B. fire protection control room side master controller, controller of fan, fire detector, fire warner, fire broadcast controller, data force transfer controller (router) are solely installed respectively and are carried out signal connection by wireless signal；Controller of fan, by being arranged on fan end, gathers fan condition information by fan condition monitoring means, sends fan condition signal to fire protection control room side master controller in real time by ZigBee transmitter unit and data force transfer controller (router)；When fire-fighting link, the control instruction that fire protection control room side master controller sends is received by data force transfer controller (router), control blower fan start and stop to stop or rotating, meanwhile, electromagnetic air valve action message is sent the master controller to fire protection control room by data force transfer controller (router)；Fire detector senses fire information by fire detection unit, sends fire alarm signal to fire protection control room side master controller in real time by ZigBee transmitter unit and data force transfer controller (router)；Fire warner, when fire-fighting link, receives master controller linkage signal, starts sound and light alarm；Fire broadcast controller, when fire-fighting link, receives master controller linkage signal, starts fire broadcast mode；
C. after fire protection control room side master controller receives fan condition information and fire-alarm information, data process is carried out by its ZigBee processor unit, showing tunnel fire hazard status information by data display unit, meanwhile, primary processor is transmitted to Fire Control Cabinet by data-interface；
D. during fire-fighting link, Fire Control Cabinet input fire-fighting link signal is to fire protection control room master controller, after master controller processing unit processes, produce air-blower control signal, after its ZigBee processor unit processes, sent to electromagnetic air valve controller by ZigBee communication unit, open blower fan and carry out fire control smoke exhausting, meanwhile, fire-fighting link instruction is sent to fire warner and fire broadcast controller, startup fire alarm and fire broadcast；After fire-fighting link releases, sending out code to controller of fan, fire warner and fire broadcast controller, display system is normal condition the most on a display screen；
E. the data force transfer controller (router) signal to receiving is processed by its ZigBee processor unit, it is judged that signal the need of force transfer, the most then carries out data force transfer, otherwise carries out dormancy.
A kind of monitoring method of intelligent wireless tunnel fire hazard monitoring system; it is characterized in that air-valve status information is wirelessly sent the master controller to fire protection control room side by blower fan side controller; fire protection linkage control instruction is wirelessly sent blower fan side controller by the master controller of fire protection control room side, controls electromagnetic air valve start and stop or rotating；Fire monitoring information is sent the master controller to fire protection control room side by fire detector, fire-fighting link signal is sent to fire warner and fire broadcast controller by master controller, carry out Signalling exchange by ZigBee unit between main control and other various controllers, then carried out the refile of signal by force transfer controller；Various initialization datas upload to the master controller of control room side also by ZigBee-network.
6. an intelligent wireless tunnel fire hazard monitoring system and method is applied not only to tunnel fire hazard monitoring, is also completely suitable for the Ventilation Control in Tunnel Ventilation System.
